ELECTRIC-METER CONSTRUCTION.

Patented Oct. 25, 1921.

Application led Iay 20, 19.18. Serial No. 235,573.

5 State of Indiana have invented anew and useful Electric-M7eterConstruction, of which the following is'a specification.

It is the object of my present invention to provide a recording meterarrangement of increased efficiency and convenience: wherein themetering parts and the record and v record-making parts are in separatecompartments; the metering parts are normally concealed but easilyaccessible; the record and record-making parts are visible and alsoeasily accessible; the metering parts have associated therewith certainliquid chambers, as for ink and for damping fluid, which are providedwith lling tubes extending into the record compartment so as to permitfilling from that compartment, so that in case of overflow theoverflowing liquid will not be in the compartment containing themetering parts; and the metering parts are in a unita ber is provided.

The present invention relates only to the general arrangement of partsand to the stationary parts. The structure and mounting-of the movableelement of the meter form the sub'ect-matter of my co-pendingapplications vot' even iiling date herewith.

The accompanying drawings illustratemy invention as applied to anelectric meter. Figure 1 is a vertical section through an electric meterembodyingA my invention; Fig. 2 is a vertical section on the line 2-2 ofFig. l; Fig. 3 isa partial section and partial elevation on a largerscale, showing the stationary frame and its mounting on the centralpartition, and the liquid compartments and their filling tubes; Fig. 4.is a plan of the frame shown in Fig. 3, with the cover of the inkchamber removed; and

Themain casing 10 of the meter is divided by a vertical partition 11into a front compartment 12 containing .the record-making parts and arearxcompartment 13 containing the metering parts. The metering -partsand the record-making parts are all supported on the partition 11. Therear compartment 13 is closed by a removable back 5,5 14; and the frontcompartment 12 is closed by a hinged front cover plate 15 which forms'the record is made b rame,lin which the ink chamer.

ment and has wlndows 16 and 17 of glass or other suitable transparentmaterial in front and top. f

Suitably mounted in the front compartment 12 on the partition 11 are tworoll brackets 2O and 21, which carry the supplyY roll 22 and the windingroll 28 of a record sheet 24. This record sheet passes over suitableguides 25 and 26 and a feed roller/27, so that it has a horizontalportion visible through the top window 17 and on which a pen 28,-and avertical portion on whlch the most recentl made part of the record isvisible throng the front window 16. The pen 28 carriesa pointer 29 whichmoves over an indicating scale 30, so that visual indication of theinstantaneous condition being measured is given. The record sheet isdriven in any suitable manner, as by clockwork, preferably inclosed in acasing 31 mounted on the partition 11 within the compartmentY 12. Thisdriving means operates the winding roll 23l and the feed roller 27, inany suitable manner. The guides 25 and 26 and the feed roller 27 arepreferably supported from the partition l1, as by being mounted eitheron the clockwork casing 31 or on a bracket 32 projecting forward fromsuch partition.

Mounted within the compartment 13 on the partition 11 is the stationarynon-magnetic frame -35 of the metering parts of the meter. This frame isof unitaryconstruction, as best shown in Fig. 3, and in the electric-meter shown carries in any suitable manner the stationary coils 36which produce the desired magnetic field. A movable lthe front, sides,and top of such compart- I element having suitably connected coils 38tion forms no part of the present invention,

and neither does the structure and mountin of the movable element, asalready state so that such movable element has been almost whollyomitted from the showing in Fig. 3. The pen 28 is carried by a clip 43suitably mounted on the staff 39 of the movable ele? ment, the precisemounting of such pen forming part of the subject-matter .of my aforesaidco-pending application Ser. No.v

bent downward to .pass through an arc-` shaped slot 44 inthe cover 45 ofan' ink well 46 and-intoI the ink in such well. The' ink frame 35, ItisV provided with "a illingtube 4:7 which passe'sfrom such well throughthe` frame the partition -11- into the eom* partnient 12. Thej'outer endof the' illing' ,tubefi' is closediby a screw148 and is provided onitsupper side with a filling open-- ing 49 through which the ink-well 46may be filled; The filling opening`49`is lower than the top of the inkchamber 46, sothat incase of overflow thexoverflow will be. in thecompartment`12 and not in the compartment 13.

Attached tothe bottom of the' frame 3.5 1s a cup 50,i into 'which-astationary-parti# tion 51 from'the `frame 35 and a'fpaddle52 carrie'd'by.a clip 53on the-lower endbfthe tube 39 extend downwar'd. The :cup 50contai-ns oil or 'other damping iuid, which-reac'ts on' thepaddle 52 -toproduce the desired .idanipin-g'- effect, YThe-cup 50 is provided" witha filling tube' 54 extending therefrom thrOu'g-hthe partition 11similarly to the y.its upperside'A inthe chamber 12,. and suchA fillingopening56 being lowerthannthe top 1 of the cup -50,`so that the cup maybe filled from thecompartment 12 and any overflow' i .se

In operation, the movable element moves -upon variations in the thingbeing measured',

and as-.it moves is damped by the reaction of the paddle 52 and-theoilin the cup 50. Also, the movements 'ofthe movable element .causecorresponding movementsfof the Apen 28, so that 'it makesaa record Vonthe record sheet 24 which is being moved" work vwithin the casing-.31.
